Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0026] First embodiment:

[0027] See also Figure 1-Figure 3 As shown, the utility model provides a fixture for machining precision parts and components, including a base 1, a fixed plate 2 and a movable plate 3 are provided on the upper surface of the base 1, wherein the movable plate 3 is slidably matched with the base 1; a mold plate 4 is detachably installed on the facing surfaces of the fixed plate 2 and the movable plate 3, and a driving component 5 is provided on the base 1 for driving the movable plate 3 to slide toward the fixed plate 2, so as to clamp the parts and components. In the use of the device, the driving component 5 can be used to drive the movable plate 3 to approach or move away from the fixed plate 2. After the movable plate 3 approaches the fixed plate 2, the mold plate 4 on the surface of the movable plate 3 and the fixed plate 2 can be used to clamp the parts and components. After the movable plate 3 moves away from the fixed plate 2, the locking of the parts and components can be released, and the parts and components can be unloaded. The operation is simple and convenient, and the use effect is good. Furthermore, the mold plate 4 can be disassembled and separated from the fixed plate 2 and the movable plate 3, and the mold plate 4 can be replaced according to the different parts and components, so as to meet the clamping use of various parts and components, and has a wide range of applications.

[0028] In a preferred embodiment, the fixing plate 2 is connected to the base 1 by bolts, and corresponding screw holes can be set on the surface of the base 1 according to the length of the parts, so that the fixing plate 2 can be installed, and parts of different lengths can be clamped and fixed.

[0029] The second embodiment is different from the first embodiment in that:

[0030] In the connection structure between the movable plate 3 and the base 1, a transverse slide groove 101 is provided on the upper surface of the base 1, and a sliding seat 301 is installed on the bottom surface of the movable plate 3. The sliding seat 301 and the transverse slide groove 101 are slidably matched, and the sliding seat 301 and the transverse slide groove 101 are used to guide the movable plate 3. Furthermore, the cross section of the sliding seat 301 is a "T"-shaped or trapezoidal structure, and the sliding seat 301 and the transverse slide groove 101 are clearance-matched;

[0031] In the installation structure of the mold plate 4, the facing surfaces of the movable plate 3 and the fixed plate 2 are provided with fixing grooves 302, and the back side of the mold plate 4 is provided with a connecting seat 401. The connecting seat 401 and the movable plate 3 are interference fit, and the mold plate 4 is installed by plugging the connecting seat 401 and the fixing groove 302.

[0032] The third embodiment is different from the first embodiment in that:

[0033] The driving assembly 5 includes a vertical plate 504, and the movable plate 3 is located between the vertical plate 504 and the fixed plate 2. A thrust spring 501 is provided between the vertical plate 504 and the movable plate 3. A strip plate 502 is slidably provided on the vertical plate 504. A thrust assembly 6 for repeatedly moving the strip plate 502 is provided on the base 1. The strip plate 502 can be pulled to move by the thrust assembly 6. When the elasticity of the thrust spring 501 is overcome to pull the movable plate 3, the movable plate 3 moves away from the fixed plate 2, and the fixing of the parts between the two mold plates 4 can be released, which is convenient for unloading the parts; when the limit of the strip plate 502 by the thrust assembly 6 is released, the elasticity of the thrust spring 501 is used to push the movable plate 3 toward the fixed plate 2, and the parts between the two mold plates 4 can be clamped;

[0034] Furthermore, a longitudinal slide groove 102 is provided on the base 1, and the thrust assembly 6 includes a sliding frame 601, the bottom end of the sliding frame 601 is slidably matched with the longitudinal slide groove 102, a matching groove 503 is provided on the strip plate 502, and the high end of the sliding frame 601 is slidably matched with the matching groove 503, and a limit baffle 602 is provided on the outer side of the sliding frame 601, and a strip member 603 that is limited by the movable end of the strip plate 502 is rotatably provided on the limit baffle 602. When the sliding frame 601 is pulled to move upward, the sliding frame 601 can be guided by the sliding match between the longitudinal slide groove 102 and the bottom end of the sliding frame 601, so that the sliding frame 601 slides vertically up and down. Since the sliding frame 601 is an inverted trapezoidal structure, the elasticity of the thrust spring 501 can be utilized. The side surface of the matching groove 503 away from the vertical plate 504 is made to contact with the sliding frame 601, so that the strip plate 502 reciprocates. In the operating instructions, the sliding frame 601 is pulled up, and the small end of the sliding frame 601 contacts the inner wall of the matching groove 503. The elasticity of the thrust spring 501 is used to push the movable plate 3 toward the fixed plate 2, so that the movable plate 3 and the fixed plate 2 are close to each other, and the parts between the two mold plates 4 are clamped. At this time, the strip piece 603 on the limit baffle 602 corresponds to the strip plate 502. The strip piece 603 is rotated so that the length end of the strip piece 603 corresponds to the strip plate 502, so as to realize the locking of the sliding frame 601, that is, the locking of the movable plate 3. The device is simple to operate and easy to use.
